Initial investigation involved the study of the fluorésence emission characteristics of XeBr, centered at 44 nm for various electron beam pumped mixtures of argon, xenon and several different bromine donors. From these experiments, formation and quenching processes were determined. Three-body collisional quenching of XeBr was identified as the primary formation mechanism for the triatomic species. Quenching rates for Xe.Br and XeBr were measured; the XeBr radiative lifetime was determined to be 245 + 3 ns. Laser experiments were performed after the kinetics of the molecule were determined. Many different parameters were varied, including gas composition and cavity characteristics. Although no definite evidence of laser action was seen, some alignment sensitive effects were noted.93 ppengCopyright is held by the author, unless otherwise indicated.
